The old timer warns the man that "no man must travel alone in the Klondike after fifty below." This foreshadows that the man will have problems or get into trouble along the way.

"Fifty degrees below zero stood for a bite of frost that hurt and that must be guarded against.... " This quotation foreshadows the danger of the weather the man is traveling through.

Another example would be the danger of the springs the man knew he had to navigate. “He knew that there were springs that bubbled out from the hillsides and ran along under the snow and ran along under the snow and on top of the ice of the creek. He knew that the coldest snaps never froze these springs, and he knew likewise their danger."
